SAFE-DOOR.

Specification of Letters Patent.

Application filed. March 5, 1908. Serial No. 419,367.

To all whom it may concern: Be it known that I, DANIEL H. RIGGAN, acitizen of the United States, residing at Warrenton, in the county ofWarren and State of North Carolina, have invented a new and usefulSafe-Door, of which thevfollowing isa specification.

This invention relates to safes of that char acter utilizing circulardoors and its object is to provide a safe door the outer surface ofwhich is imperforate and void of all projections so that the openingofthe safe by unauthorized persons is rendered more than heretofore.

A further object is to provide a circular door designed to rotaterelative to the safe.

body so as to operate tumbler mechanism of.

ported in a novelmanner whereby the same 7 when released can besupported beyond and at an angle tothe safe body, said supporting meansbeing foldable into the body during the closing of the door.

With theseand otherobjects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure .1 is a horizontal section through the safedoor and apo'rtion of the safe body, the outer part of the 'door beingshown in plan. Fig. 2 is a sideelevation of a portion of the door, theadjoining portions of the safe body being shown in section. Fig. 3 is arear elevation of the outer or movable section of thedoor. .Fig. 4 is anelevation showing the outer face of the inner section of the door. y

Referring to the figures by characters. of reference, 1 designates thesafe body, the same being provided with adoor opening2 circular in form.Theinnermost portion of thisZdoorZopeninglisl'preferablyltapered as inedifficult p of pivotally connected members 8 designed dicated at 3 toconstitute a seat for the inner portion of the door when closed. Anouter portion of the door opening is stepped annularly as indicated at 4to form shoulders constituting abutments for the outer portion of thedoor. An annular groove 5 is formed within one of these steps and theouter wall 6 of the groove is provided at suitable points with slots orrecesses 7 for the purpose hereinafter set forth.

Pivotally connected to the safe body and inrear of the space occupied bythe door when closed is a hinge made up of a plurality to-fold togetherwhen the door is closed and 'theouter member of which is pivotallyconnected to one or more ears 9 extending inwardly from the inner faceof the inner door :section 10. This door section is preferablycylindrical for the greater part of its length,

its inner portion, however, being tapered as at 11 so as to fit snuglyagainst the corre sponding tapered or reduced portion 3 of the dooropenin 2. This section 10 contains suitable tum ler'mechanism 12 whichmay be of the ordinary or any preferred construction and is designed toactuate bolts 13 which are slidably mounted within section 10forengagement with sockets 14 located in the wall of the dooropening.The outer face of sectlon 10 is provided fwith a circular groove 15concentric with the center thereof, the inner portion of said groovebeing extendedlaterally as at 16 so that. the groove'issubstantiallyT-shaped in cross section. At desired intervals, referablydiametrically oppositepoints, t e slot 7 15 is enlarged transversely asindicated at 17.

These enlargementsare designed to receive T-shaped retaining lugs 18extending from the inner face of the circular outer door section 19.This section fits snugly against the section 10 and the spindle 20,which actuatestumblers 12 and is revolubly mounted within section 10, issecured to the middle portion of thissection 19 preferably by ro-,v1dingitwith a winged or an ular end he d in a recess in secti0n19 by aling 19 of soft metal so that by rotating section 19 the spindle will beoperated to actuate the tumblers. ,This section 19 is stepped annularlyso asto fit snugly against the shoulders within the stepped portion 4 ofthe door opening and exten ng radially from the section 19 are retainingand locking studs or rojections 21 preferably carrying antirictionrollers 22 and designed, when the door is moved into closed position, topass through the recesses or slots 7 so as tobecome seated within theannular groove 5. Section 19 is preferably so constructed that as soonas projections 21 have been insertedthrough the recesses 7 the door willturn automatically for a short distance, this turning operation beingproduced either by adding Weight to the door at one side of its centeror by removing metal therefrom, as has been indicated at 23 in Figs. 1and 3. As the spindle 20 is secured at one end to section 19 and at itsother end to the tumbler mechanism 12 which is held against removal fromthe section 10, said spindle will act to securely hold the two sections10 and 19 together and prevent them from becoming separated when thesafe is opened.

Suitable graduations and numbers may be placed upon the outer face ofsection 19 close to its periphery and these numbers and graduations caneither be formed in or upon the door sections or the part provided withsaid numbers and graduations can be removed therefrom and foldable so asto be conveniently carried.

When it is desired to open the door which has been described, the handsof the operator are placed flat against the outer surface of thesections 19 and byturning them said sections will move therewith, theprojections 18 traveling in a circle and within the groove 15. Section10 does not rotate, it being held against rotation by the members 8. Itwill be apparent therefore that section 19 will operate the spindle 20and by turning said section 19 backward and forward in the same manneras the knob of an ordinary combination lock is turned, the tumblers 12can be shifted so as to ultimately retract the bolts 13 from the sockets1 1. As this bolt actuating mechanism constitutes no part of the presentinvention it has not been disclosed in detail. After the bolts have beenretracted section 19 is turned until the studs 21 register with therecesses 7 whereupon the door can be opened outwardly. The members 8permit the door to be moved outward and to be swung relative to the bodyof the safe. When it is desired to close the safe the door is pushedinto the opening 2 thus causing the hinges 8 to fold into the safe. Thestuds 21 are of course positioned so as to move through the recesses 7and into groove 5. As soon as the door has been seated in this mannerthe section 19 is turned in either direction so as to cause the bolts 13to be projected into sockets 14. This partial rotation of the section 19can be performed by the operator, although it is not necessary as thedoor section 19 will automatically partly rotate as soon as releasedbecause one-half thereof is heavier than the other as heretofore eX-plained so as to promptly move the studs 21 out of register withrecesses 7. It is to be understood that friction between the sections 10and 19 can be reduced in any preferred manner as by interposing balls orrollers between the bearing faces of the parts. Such a constructionhowever, is so common that illustration thereof is not deemed necessary.It is of course to be understood that the sections 10 and 19 can bereadily assembled by inserting the projections 18 into the enlargedportions 17 of groove 15, after which section 19 can be partly rotatedrelative to the section 10 and the two parts thus securely heldtogether. During the manipulation of the tumblers 12 in the mannerhereinbefore set forth the spindle 20 will of course prevent separationof the two sections 10 and 19 whenever the projections 18 mow intoregister with the enlarged portions 17 of the groove 15.

A safe door comprising movably connected sections, one of saidsections being revoluble relative to the other section, the two sectionsbeing held against independent movement in the direction of their axes,locking members carried by one of the sections, and means operated bythe movement of the revoluble section for actuating said lockingmembers.
